<p>The Logo Killer Filter is an early attempt to deal with station logos added
on to TV broadcasts.</p>
<p>It currently operates in one of three modes:<ol>
<li>Grey. In this mode the square selected is replaced by a grey square </li>
<li>Limit to Max Value.  In this mode all internal luma values over a specified 
maximum are clipped to a specified maximum</li>
<li>Dynamic Max.  In this mode the top and bottom egdes are used to calculate a 
dynamic maximum, all intenal luma values are then clipped to this maximum</li>
</ol></p>
